Murderer. Munroe was a noted architect in New Brunswick. Although married he began to have an affair with Maggie Vail, who later had his child. In 1868 Maggie Vail and her child were both murdered on Black River Road in Saint John, New Brunswick. The remains of the two victims were found a year later and Munroe was arrested and charged with the murders. Munroe was later found guilty and sentenced to death. After a plea to the Governor General, and a petition from 2,000 people was presented, and denied, the death sentence was carried out. The story was very big at the time and was the subject of the book,"The Maggie Vail Story" by Ruby Cusack. (bio by: K)
